Key Properties & Advantages

• Exceptional Thermal Conductivity: Ranges from 33–60 W/m·K (h-BN), facilitating efficient heat dissipation.
• Outstanding Electrical Insulation: High volume resistivity, up to 10¹? Ω·cm, ensuring reliability in high-voltage environments.
• Superior Thermal Stability: Withstands temperatures up to 1900°C in inert atmospheres and 850°C in air, with excellent resistance to thermal shock.
• Excellent Machinability: Due to its low hardness and layered structure, it can be easily precision-machined into complex shapes using conventional metalworking tools.
• High Chemical Inertness: Resistant to corrosion from most molten metals, acids, and salts.

Primary Applications

• High-Temperature Insulators and components for semiconductor manufacturing equipment.
• Crucibles for metallurgical processes and CVD/PBN components for crystal growth (e.g., GaAs, InP).
• Insulating Parts in lasers, plasma arc fixtures, and electron beam evaporators.
• Precision Components requiring high thermal conductivity and electrical insulation.
